The intra-prostatic "partial catheter" (urological spiral) represents a completely new idea. The material is metal and it enables a patient to discard his indwelling catheter. Most of the time made of rubber or plastics. The spring-shaped spiral inserted in the prostatic urethra keeps the enlarged prostate lobes compressing the urethra so far apart that spontaneous voiding is again possible. The physiological function of the external sphincter is maintained due to the special form of the spiral. Voiding is effected without residual urine. By eliminating continuous contact with the outside ascending infections will no longer occur and infections already existing will heal spontaneously. The possibility of treating prostate carcinoma later on by using radioactive material with which the spiral inserted could be coated is also discussed.
前列腺内“部分导管”（泌尿外科螺旋装置）代表了一种全新的理念。该材料为金属材质，能使患者摆脱留置导尿管。目前的导尿管大多由橡胶或塑料制成。插入前列腺尿道的弹簧状螺旋装置可使增大的前列腺叶保持足够距离，不再压迫尿道，从而再次实现自主排尿。由于螺旋装置的特殊形状，外括约肌的生理功能得以维持。排尿时无残余尿。消除了与外界的持续接触，上行感染将不再发生，已有的感染也会自行愈合。文中还讨论了日后使用放射性物质包裹插入的螺旋装置来治疗前列腺癌的可能性。
